java timer关闭_java – 如何停止正在运行的TimerTask

您需要通过调用以下方法取消计时器

timer.cancel(); // Terminates this timer, discarding any currently scheduled tasks.

timer.purge(); // Removes all cancelled tasks from this timer's task queue.

这将取消任务,所以这样的事情会起作用：

import java.util.Scanner;

import java.util.Timer;

import java.util.TimerTask;

import java.awt.Toolkit;

class Alarm {

private static boolean run = true;

public static void main(String[] args) {

long delay;

Scanner scan = new Scanner(System.in);

System.out.print("Enter a delay in seconds: ");

delay = scan.nextInt()*1000;

final Timer timer = new Timer();

final TimerTask task = new TimerTask() {

@Override

public void run() {

if(run) {

Toolkit.getDefaultToolkit().beep();

} else {

timer.cancel();

timer.purge();

}

}

};

timer.schedule(task, delay);

// set run to false here to stop the timer.

run = false;

}

}
